BURNER.

, Application filed Iay.22, 1925. Serial No. 32,101.

This invention relates to side .feed gas burners and more particularly to gas burners for use in connection with water heaters in which the water. supply or circulating syso tern includes a vertical pipe at the bottom of the heater around which the burner is located and must be assembled;

The object of the invention is to provide a burner of the kind described which is of simple construction and can be made at low cost; which is so arranged as to enable it to be readily attached to or removed from the heater without disturbingthe water connections; which is firmly and rigidly supported l5 when in use; and which properly distributes the gas jets over the horizontal area with proper provision for the supply of air to secure eflicient combustion and maximum heating efiects. ,7 v

In the drawings, which represent one embodiment of the invention, Fig. l i s ahorizontal sectionon'the line 11, Fig. 2; Fig. 2

is a sectional elevation on the line 2-2, Fig.

1, showing the burner applied to the lower portion of a water heater; Fig. 3 is an inverted plan view of the central portion of the burner; and Fig. 4 is a detail section, on

a larger scal'e, on the line 4.--1, Fig. 1.

Referring to the drawings, 1 indicates the casing or jacket of an ordinary gas burning water heater, said jacket being of any su-it.

able construction with or without a door or doors, as desired. For convenience of illustration, it is shown as including a depending flange or skirt 2 provided with a plurality of lugs or ears 3 which serve as seatsfor the burner to be described. ,Within the chamber of said jacket, and through which chamber the heated products of combustion rise from the burner, is located the water container or heater, shown as a hollow memher 4 with a vertically centrally disposed bottom water supply pipe 5, through which, water flows into the container 4 to be discharged therefrom through the .upper outlet pipe (not shown) as is usual.

The burner forming the subject matter of the present invention may be made of. any suitable'form, but is usually asingle hollow member, such as a cored casting. provided at the proper or any desirable places'with lugs-or ears 6 adapted to rest upon the jacket seats 3 and to be secured thereto by bolts 7, if desired. One portion of the casting. marked 8, is of-hollow tubular form and serves as the lateral or side supply for the mixture of gas andair introduced into the usual valved Bunsen inlet 9. The burner as a whole, excepting for desirable or necessary unequal spacing of the lugs 6, as shown, is. symmetrical about a vertical plane through the axis of the tubular mixture supply portion 8 and includes two oppositely disposed substantially semi-Circular outer chambered portions 10 from which the lugs .or ears 6 extend, said outer semi-circular portions being connected by cored radially extending portions 11 to the base of a-U shaped portion 12, the arms or side members 12" of which are parallel and extend from the radial portions 11 to-the ends of thesemi-circular portions 10 and which arms between them form an open ended slot or recess 13 extending from the outside of the burner to its center and in alignment with the tubular portion 8; This slot enables the burner to be pushed into place from one side and properly assembled about the'water pipe 5, so that the burner may be assembled with the jacket-after the water connections have been made, or may be removed from the jacket for cleaning or replacement after installation.

When the burner ispushed home or to the position shown in Fig. 2, the pipe 5 rests against a plurality. two being shown, of pads or blocks 14 cast integrally with the burner and located near the base of the U portion 12. Opposite each of said pads and located on the bottom of each of the arms 12 of the U shaped portion 12 is an adjustable set screw 15, which set screws may be screwed home after the burner is assembled about the water'pipe, as shown in Fig. 3, in order to clamp it firmly in osition. Of course, the outer end of the mlxture supply portion '8 is supported by the gas pipe which supplies gas to the burner mixture, as is usual. All portions of the burner.-including the outer semi-circular portions 10, the radial portions 11 and the U shaped portion 12 are cored or chambered, the passages and chambers therein communicating with each other and with the chamber 16 in member 8. It will be observed that the mixture of gas and air is carried by member 8 practically to the center of the burner and then distributed by the shortest possible paths to all parts of the burner from which'it issues in a plurality of jets through the perforated I teats 17 distributed uniformly over the upper surface of the burner. The arrangement of the several chambered portions of the burner supplies a series, four being shown, of openings 18, which with the. slot 13, break up the otherwise flat surface of the burner and enable air to be supplied between jets and thereby promote'combustion. Each jet, in the burner shown, is closely contiguous to an o ening to the burner and through which air is supplied to said jet.

What I claim is:

1. A side gas burner for heaters of the type including a substantially vertical pipe, comprising outer oppositely disposed substantially semi-circular chambered portions.'

and a substantially U-shaped chambered portion spaced therefrom and connected thereto, said substantially U-shaped portion having its arms spaced to form an open ended slot extending from one side of the burner to the central axis thereof for lateral assembly of the burner with the vertical pipe, and

'a mixture feeding portion having a passage in communication with the chambers of said semi-clrcular and U-shaped portions" 2. A side feed gas burner for heaters ofthetype including a substantially vertical pipe, comprising outer oppositely disposed substantially semicircular chambered portions and a substantially U-shaped chambered portion spaced therefrom and connected thereto, said substantially U-shaped portion having its arms spaced to form an open ended slot' extending from one side of the burner to the central axis thereof for lateral assembly of the burner with 'the vertical pipe, and a mixture feeding portion having a passage leading to the base of the chamber of said U-shaped portion and communicating also with the chambers of said substantially semi-circular portions.

3. A side feed gas burner for heaters of the type including a substantially vertical pipe, .comprising outer oppositely disposed substantially semi-circular chambered portions and a substantially U-sh'aped chambered portion connected thereto by radially extending chambered portions, said substantially U-shaped portion having its arms spaced to form an open ended slot extending from one side of the burner to the central axis thereof for lateral assembly of the burner with the vertical pipe, and a horizontally extending mixture feeding portion in alignment with said open ended slot and having a passage in communication with the chambers of said semi-circular portions, said radially extending portions and said U- .shaped portion.
